Looking to get the most out of your G8x M3/M4? Fabspeed has the answer with our Turbo Back Exhaust Package. Starting with our Sport Cat Downpipes that feature high quality HJS catalytic converters. This guarantees the most exhaust flow, reliability, and sound. Then, we use our unique intermediate X-Pipe that features two X-Pipes for proper exhaust scavenging and sound balance. And finally our Valvetronic exhaust, which features Helical Valves from the U.K. that are plug and play with the factory valve controllers. This system is your ticket to bolt on sound and performance without any loss of functionality or CEL’s (Check engine lights).
SOUND:
Treat your ears to that iconic BMW straight six symphony! You’ll no longer have to suffer the anemic OEM sound that BMW blighted this model with. The whole tone of the exhaust changes, with a throaty note that sounds every bit of the 500 HP you have on tap. In the loudest M setting, the exhaust is deep and powerful with very loud and prominent overrun pops and burbles. You’ll actually hear the turbos spool when letting off the throttle. With the car in comfort mode, things are much more tame. No pops/burbles and drone is nowhere to be found. In cabin conversations are just as easy as they were with the stock exhaust system.
POWER:
Our full Turbo Back Exhaust Package really frees up exhaust flow on the G8x. On our in-house DynoJet, we saw max gains of 47 ft/lbs of TQ at 3,300 RPM and 41 WHP at 6,500 RPM. That’s 47 crank HP! Take a look at our dyno graph and you can see that power is gained throughout the entire power band.

FEATURES:
Driving will become your new favorite pastime with our BMW G82 M4 exhaust installed! Among our most revolutionary turbo-back exhaust packages, this precision-tuned G82 M4 upgrade is a must-have transformation if you want to feel, hear, and enjoy the power of your BMW like it was meant to be experienced!
The power gains and exhilarating tone begin with liberated exhaust flow and provide a deeply engaging experience. Through all stages of the G82 M4 exhaust, we have optimized key parameters such as introducing wider-diameter piping, sound, and power-enhancing x-piping, and precision-tuned helical valves that allow you to unleash your BMWs raw potential at will.
The result is a dynamic and more enjoyable driving experience that is brought to life through:
Fabspeed Sport Cat Downpipes: Enhanced emissions scrubbing meets liberated exhaust flow with our superior sport cat downpipes! Direct from our top-rated partners at HJS, our premier 200-cell catalytic systems take clean-burning exhaust performance to the next level.
Fabspeed Intermediate X-Pipe: Our dual x-pipe intermediate pipes are engineered to bring out the best in sound and exhaust flow. Wider, stronger, and less restrictive than the stock components, this dynamic addition brings a cohesive balance to the exhaust equation.
Fabspeed Valved Exhaust: Completing the exhilarating exhaust upgrade, our unparalleled Valved Exhaust system synchronizes with the factory valves for seamless functionality for breathtaking gains in M mode and enhanced cruising in comfort mode.
For step-by-step BMW or Porsche Cayman exhaust system installation assistance, contact our experts for a personalized build consultation, or let them handle the upgrade on your behalf!
Are you looking for other 5-star exhaust components, intake upgrades, or other luxury enhancements for your BMW? Our courteous and experienced performance experts are here to help.
Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.
DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only, never to be driven on public roads. This product is or contains a Racing Cat Bypass Pipe, which will give you check engine lights on OBD2 cars. We suggest pairing this product with racing software to prevent fault codes and check engine lights. Racing Cat Bypass Pipes are solely intended for track and race cars as they are NOT California Air Resources Board Certified (CARB) and not EPA certified. You are hereby informed and warned to check your local, state, and federal laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.
